Halo 3 co-op confirmed

, Halo 3 developer Bungie has finally confirmed that its upcoming Xbox 360 FPS will indeed offer co-operative play in its campaign mode.

Up to four gamers will be able to hook up over Xbox Live, or alternatively, two machines hosting split-screen play will be able to join forces via system link.

It has also been revealed that in an effort to maintain narrative credibility, only player one will be allowed to play as the Master Chief. Player two will assume the role of the Arbiter, whilst players three and four will be able to choose between two new Elite characters.
